The aim of the OWL: Experiences and Directions Workshop (OWLED) is to establish an international forum for the OWL community, where practitioners in industry and academia, tool developers, and others interested in OWL can describe real and potential applications, share experiences and discuss requirements for language extensions/modifications.

OWL has become the representational model of choice for supporting interoperability in many industries. With its rise in popularity, as well as the number of publicly available ontologies, it becomes important to focus on the processes by which ontologies can be engineered through reuse.

In this edition of OWLED we aim to bridge the gap between ontology engineering practices and software engineering, where reuse is common practice, and we welcome submissions of papers describing reuse methods employed throughout the ontology development cycle; modeling / terminological decisions, alignment and comparison between ontologies, how ontologies are stored, versioned, distributed, and consumed over the Web. As with previous editions, we also welcome proposals for improving the OWL standard.

The goal of the OWL Reasoner Evaluation (ORE) workshop, is to bring together the developers and users of reasoners for (subsets of) OWL 2, including systems focusing on both intensional (ontology) and extensional (data) query answering. The workshop will give developers a perfect opportunity to promote their systems.
